Field Installation Guidelines
Align probe tip perpendicular to shaft surface for accurate displacement readings.
Maintain coaxial shielding integrity; ground only at the Proximitor end.
Route probe cables away from high-voltage conductors to minimize EMI.
Confirm gap voltage (–9 VDC to –11 VDC nominal) during commissioning.
